The GOP Senate nominee gave $75,000 to the pro-Mitt Romney Super PAC Restore Our Future, according to the Center for Responsive Politics. The Washington, D.C., organization tracks the role of money in campaigns.

So did her husband, Vince McMahon.

Together, the co-founders of World Wrestling Entertainment, now the WWE, have contributed $356,000 during the 2011-12 election cycle to the Republican Party and candidates such as House Speaker John Boehner, R-Ohio, and Sen. Scott Brown, R-Mass.

A spokesman for McMahon, who has spent at least $65 million of her money on back-to-back Senate candidacies, had no comment.

In contrast, U.S. Rep. Chris Murphy, D-Conn., who is pitted against McMahon in a toss-up race, made no such contributions, according to a records search under his name.

In Connecticut, McMahon contributed $1,000 to Wayne Winsley, the GOP nominee in the 3rd Congressional District represented by Democrat Rosa DeLauro, and $1,000 to Justin Bernier, who lost a four-way primary last month to Andrew Roraback in the 5th Congressional District.

McMahon gave $2,500 to Romney's presidential campaign, on top of the $75,000 she gave to the Super PAC supporting the former Massachusetts governor.

Romney's core supporters from Connecticut have contributed $2.8 million since last year to Restore Our Future.

The rise of Super PACs has given donors like McMahon an additional conduit to help their candidate. So far during the presidential campaign, the Republicans have benefitted more from super PACs, committees which have to operate independent of a candidate's operation and don't labor under the same donor restraints that are on candidate and party committees.
